Mar 15, 2021 Explore the fascinating neuroscience of attention and how our brains filter sensory information. Learn about the parietal cortex's pivotal role in focus and perception, and discover the intriguing condition of neglect, where individuals can't recognize stimuli on one side. The discussion highlights how attention is both a limited resource and essential for everyday functioning. Uncover the mechanics of how we 'pay' attention and the implications of these processes in our daily lives.

Episode notes
Attention as a Perceptual Filter
- Attention acts as a filter allowing sensory information to reach perception.
- Without attention, sensory input doesn't become part of our conscious awareness.
Parietal Cortex Amplifies Attention
- Neurons in the parietal cortex amplify signals where attention is focused, increasing perception.
- This neuronal firing acts like a spotlight intensifying sensory information at the attended location.
Attention as Limited Resource
- Attention is a limited resource that can only be allocated so much at once.
- Overloading attention with tasks reduces amplification for important sensory input, causing missed information.
